Abstract

Several cation-pi complexes between substituted [n.n]paracyclophanes (n = 2, 3) and cations have been studied using high level ab initio calculations. The chemical substitution at the aromatic ring that is not interacting with the cation has a strong influence upon the binding energy. This strong through-space substituent effect has been studied using the "atoms-in-molecules" theory, which has been found useful to explain the energetic results.

摘要

已使用高水平从头算计算研究了取代的[n.n]对环芳烷（n = 2, 3）与阳离子之间的几种阳离子-π配合物。不与阳离子相互作用的芳环上的化学取代对结合能有很大影响。已使用“分子中的原子”理论研究了这种强烈的空间取代基效应，发现该理论有助于解释能量结果。
